Description

A wedge-type centering tensioning fixture for machine tools

Technical Field

The present application relates to the technical field of tooling fixtures, and in particular to a wedge-type centering and tensioning tooling fixture for machine tools.

Background Art

In the process of motor manufacturing, the motor housing is an indispensable part. The most important component on the housing is the heat sink located on its outer wall. During the manufacturing process of its outer shell, it is often necessary to drill holes in the motor shell and grind and polish the heat sink. In this process, the position of the cylindrical housing needs to be limited.

When grinding and polishing a cylindrical housing, it is necessary to rotate the housing around the axis of the cylindrical housing. The housing is fixed by clamping the housing wall with a common fixture. This will cause the housing to have a certain weight when the housing stops rotating after grinding and polishing, so that the housing will have a certain inertia, but the fixture will stop rotating immediately. Therefore, the fixture will cause certain wear on both the outside and inside of the housing, which will affect the appearance of the housing and affect the sale of the housing. Therefore, those skilled in the art provide a wedge-type centering and tightening machine tool fixture to solve the problems raised in the above background technology.

Utility Model Content

In order to solve the problem that when grinding and polishing a cylindrical casing, the casing needs to be rotated about the axis of the cylindrical casing. An ordinary tooling fixture fixes the casing by clamping the casing wall to fix it. This will cause the casing to have a certain weight when the grinding and polishing is completed and the casing stops rotating, so that the casing has a certain inertia, but the fixture will stop rotating immediately. Therefore, the fixture will cause certain wear on the outside and inside of the casing, which will affect the appearance of the casing and affect the sale of the casing. The present application provides a wedge-type centering and tightening machine tool fixture.

The present application provides a wedge-type centering tensioning machine tool fixture that adopts the following technical solution:

A wedge-type centering and tensioning fixture for machine tools comprises a fixed plate, both sides of which are provided with first slide grooves, a driving mechanism is installed in the first slide groove, a connecting rod is installed at one end of the fixed plate, and a clamping mechanism is installed at one end of the connecting rod.

Preferably, the driving mechanism comprises a motor and two threaded rods, the motor is mounted on one side of the top end of the fixing plate, and the two threaded rods are rotatably mounted in two first sliding grooves respectively.

Preferably, a driving wheel is fixedly mounted on the output shaft of the motor, a driven wheel is mounted on one end of each of the two threaded rods, and the driving wheel and the two driven wheels are connected to each other via a transmission belt.

Preferably, sliding blocks are slidably installed in the two first sliding grooves, and the middle parts of the two sliding blocks are threadedly connected to the two threaded rods respectively.

Preferably, the clamping mechanism comprises a first mounting plate, one end of which is fixedly connected to the connecting rod, and inclined wedge blocks are rotatably mounted on all four sides of the first mounting plate.

Preferably, the clamping mechanism also includes a second mounting plate, which is provided with second sliding grooves on all four sides, and the bottom ends of the four inclined wedge blocks are respectively slidably mounted in the four second sliding grooves, and the inner sides of the four inclined wedge blocks and the four second sliding grooves are all arranged obliquely.

Preferably, connecting plates are fixedly mounted on both sides of the second mounting plate, and two push rods are fixedly mounted between the connecting plates and the sliding blocks on two same sides.

In summary, this application includes the following beneficial technical effects:

1. By setting the driving mechanism, by starting the motor, the motor drives the two threaded rods to rotate through the active rotating wheel and the driven rotating wheel, so that the two sliders slide in the two sliding grooves respectively, and then drive the push rod to push the two connecting plates, so that the two connecting plates drive the second mounting plate to move, and it is convenient to adjust the position of the second mounting plate by controlling the rotating wheel of the motor, and then adjust the inclination angle of the inclined wedge block;

2. The casing is mounted on the machine tool through the clamping mechanism, and the outer side of the inclined wedge block is located on the inner side of the casing. The second mounting plate is moved by starting the motor. Since the second slide groove and the inner side of the inclined wedge block are both obliquely arranged, the movement of the second mounting plate drives one side of the inclined wedge block to rotate on the first mounting plate, thereby moving the other side of the inclined wedge block and pressing the other side of the inclined wedge block against the inner side of the casing, thereby fixing the casing, and conveniently and quickly fixing and installing the casing, thereby improving the processing efficiency.

The motor 31 is mounted on one side of the top of the fixing plate 1, and the two threaded rods 32 are respectively rotatably mounted in the two first slide grooves 2. The threaded rods 32 are rotated to facilitate the rotation of the two sliders 6, so that the two sliders 6 slide in the two slide grooves, and then the push rod 8 is driven to push the two connecting plates 7, so that the two connecting plates 7 drive the second mounting plate 53 to move.

1 and 2, the output shaft of the motor 31 is fixedly mounted with a driving wheel 33, one end of each of the two threaded rods 32 is mounted with a driven wheel 34, and the driving wheel 33 and the two driven wheels 34 are connected to each other through a transmission belt. By starting the motor 31, the motor 31 drives the two threaded rods 32 to rotate through the driving wheel 33 and the driven wheel 34, so that the two sliders 6 slide in the two slide grooves respectively, and then drive the push rod 8 to push the two connecting plates 7, so that the two connecting plates 7 drive the second mounting plate 53 to move, and by controlling the rotation of the motor 31, the position of the second mounting plate 53 is adjusted, and then the inclination angle of the inclined wedge block 52 is adjusted.

By starting the motor 31, the motor 31 drives the two threaded rods 32 to rotate through the active rotating wheel 33 and the driven rotating wheel 34, so that the two sliders 6 slide in the two sliding grooves respectively, and then the push rod 8 is driven to push the two connecting plates 7, so that the two connecting plates 7 drive the second mounting plate 53 to move, which is convenient for controlling the motor 31. The second mounting plate 53 is rotated to adjust the position of the second mounting plate 53, and then the inclination angle of the inclined wedge block 52 is adjusted, so that the second mounting plate 53 moves. Since the second slide groove 54 and the inner side of the inclined wedge block 52 are both obliquely arranged, the movement of the second mounting plate 53 drives one side of the inclined wedge block 52 to rotate on the first mounting plate 51, so that the other side of the inclined wedge block 52 moves and the other side of the inclined wedge block 52 is pressed against the inner side of the casing, so that the casing is fixed, and the casing can be fixed and installed quickly and conveniently, thereby improving the processing efficiency.
